First trimester prenatal diagnosis of chondroectodermal dysplasia (Ellis–van Creveld syndrome) with ultrasound

Abstract

Chondroectodermal dysplasia (Ellis-van Creveld syndrome) is an autosomal recessive condition characterized by short-limb dwarfism, postaxial polydactyly, ectodermal defects, and congenital heart disease. This condition is most prevalent in the Amish population of Lancaster, Pennsylvania, USA, occurring in 1/5000 births and in 1/60,000 births in the general population. This report presents a case of ultrasonographic detection of chondroectodermal dysplasia at 12 weeks of gestation.
